摘要： The present invention is directed to a method for making a sulfur tolerant alumina, that includes the steps of: forming aluminum hydrate from one or more water soluble aluminum salts, said salts each comprising an aluminum cation or aluminum anion and an oppositely charged counterion, in an aqueous medium, contacting the aluminum hydrate with a silica precursor in the aqueous medium and in the presence of counterions of the one or more aluminum salts, isolating silica precursor-contacted aluminum hydrate particles from the aqueous medium, and calcining the silica precursor-contacted aluminum hydrate particles to form particles of the sulfur tolerant alumina.
